TRGB Fuel Pump Kit Installation


Recommended Posts

I bought TRGB's fuel pump kit in their sale last week, I'd been prevaricating over replacing the Lucas pump as I felt the kits were overpriced when you look at the components prices, however a combination of TRGB's sale price and the certainty that the kit would fit swayed me. I was disappointed to discover that there were no instructions whatsoever included, if anyone has fitted one of these kits, could you possibly post a pic of how it goes together? I'm not even sure whether it is supposed to be mounted inside or outside of the car. My pic shows the new parts in front of my existing setup.

Ian,

I “engineered” the entire system myself en then ordered all parts, they had to come from several different vendors. It took me a lot of time, but now I have a system that is exactly as I want it. The effort (time)  for this was significant, so although the kits seem expensive, it saves you all the time. And the companies have probably spent a lot of time getting it right.

not having an installation instruction is not good, obviously, have you asked TRGB?

looks like the filter mounted with the pump is the discharge (pressurized) filter.

The smaller filter is the suction filter.

do not use jubilee clips on the pressurized side (hose from filter to PRV), your existing braided hose may probably fit, and rhat looks fine. Check coupling size/shape.

I would install the pump and discharge filter in the boot, as low as possible, and as far to the front of the boot on the left side (passenger side for UK), where your current CAV filter is, but a bit lower.

Before any drilling, check if spare wheel still fits.

The small filter is located below the tank, and connects tank to pump-inlet.

 

Electrics: use a fused relay and good earth, lots of info on the forum about that.

Good luck,

Waldi

Thanks Waldi, I have mailed TRGB and will see what their response is. The braided hose does look to be the same size. I also bought their wiring kit, again no instructions, it almost makes sense but the power feed wire isn't long enough to reach the engine bay so I'm not convinced I've thought that through properly.

Thanks Andrew, great pics, what they show is that the kit I have is assembled to be installed outside the car, if it were mounted internally the pump would be on the top, the filter assembly below the tank is way too long and is supplied with a large rubber grommet, presumably to use after you've cut a hole through the spare wheel well. I'm not remotely interested in doing that. It would be easy enough to dismantle the pump & filter mount and swap them around, I just need to see what they can do about the tank filter, it's way too long to fit without kinking the feed pipe.

Ian

 

Update - TRGB do clearly state this is designed for external mounting, my mistake for not reading carefully.

I saw a TR6 being restored by TRGB and the kit was installed in the wheel arch and looked very neat and would operate much cooler than in the boot. Touring in Spain earlier this year, we had a number of PI cars with over-heated Bosch fuel pumps - it was 38C. So i would recommend following their instructions (once you get them).

Thanks Mick, I'll see if they send anything, I'm not keen on drilling holes in the body though, the wiring doesn't come with any protection either (it does on their ad pic) I just see this as a failure point in an exposed position.

Hi Ian,

The pump fits outside the boot. They should have given you a A4 sheet showing the holes to drill. Providing you have suitable step drill (£5) it's a doodle to fit. The cool outside air keeps everything cold. Even on the hottest day this summer my pump never got hot. 

It's a neat kit and very reliable. If you struggle, please let me know as I still have the instructions.

Hi Ian

I have the TRGB Bosch pump kit which was actually fitted by TRGB in 2014 prior to my ownership of the car and it is designed to fit in the wheel arch for two reasons, it keeps the pump cooler and fitting in the wheel arch is lower than the boot to maximise the fuel flow from the tank. They also installed a larger tank union  to also aid flow. The kit is the same as yours apart from the  brackets which are the same as Andrews.

Basically the filter is in the same position as Andrews maybe a bit lower and the pipe from filter to pump runs along the floor and out through a drilled hole and gromet on the boot wall.  Pump is then installed just below in the arch.  I think it would be fairly easy to install.  I did change their pre filter as it became clogged up and being a pre filter doesn't need to be so fine at around 10 micron.  I swopped it for a Bullit filter which is 55 micron with optional metal filter. I think its the same as Andrews.  I think Prestige also use the Bullit filter in their kit

I also bought the TRGB wiring kit and was very disappointed as it doesn't come with a uprated wire to the pump which I thought was the main point of it. The relay is meant to be secured in the passenger footwell near the flasher unit and main live wire should reach the battery via the drivers side on the positive terminal. I then installed a uprated wire to the pump as this recommended  as the Bosch pump can draw up to 10 amps.

Hope this helps

regards

Roger

Thanks Roger, I would have expected an uprated wire too, again there were no instructions with this kit. It's too dark to go & look now but I don't see as the wiring is long enough to have the relay in the passenger footwell though, I'll see if I get any instructions from TRGB tomorrow.

Is Andrews pump not fitted in the boot or am I missing something. I have just had a new Bosch pump fitted and it looks like it’s in the very same place as Andrews. The only problem I have with it is the smell from the fuel permitating through the rubber hose, I have now ordered a PTFE lined hose to combat this on Andrews advice

Andrew's is in the boot, however the TRGB kit is designed to be fitting outside, the filter assembly is too long for in boot use, it is designed to pass through the spare wheel well.

I've always liked the idea of mounting the pump in the wheel arch, is there some sort of cover with the kit to protect it from muck & debris thrown up from the rear wheel?

Richard.

No Richard, nothing in the kit.

Richard, I have seen a cover supplied by other suppliers, but not by TRGB as far as i know. However, surprisingly it doesn't get that dirty and both pump and filter are sealed units. Only the wiring to worry about!.

Hi Paul,

I would be very careful with PTFE hoses that are offered by some of the Injection Specialist as they are totally unsuitable because of their 1000 psi rating which means that they have no give in them and causes the dreaded harmonic hammering as many people have found out in recent years! You do not need a hose, that is rated at 1000psi.? That is why they are now offering the diaphragm PRVs. I use Gates barricade Hose which is very flexible and meets SAE Spec 30R9 for permeation and up to 85% ethanol, meant to be the best elastomer  on the market. I have been using this spec hose for the last 3 years without any problems.

Hi Bruce

i have heard that. The one I have ordered is the Revington one which I think is OK

Hi all this is where I put the pump and filter under the left rear wheel arch. There is no longer any pipework in the boot the delivery to the filter leaves the tank directly underneath along the top of the fuel pump /filter and enters the filter at the rear of the photo the pump discharge goes to the prv that is mounted on the chassis  bracket and onwards to the MU or returns to the tank in the usual way. I have also mounted a Lucas type pump in a similar way using the saloon mounting bracket and a standard CAV filter. The electrics pass into the boot where a relay is situated, this can incorporate a tracker/ anti theft device. Never had any bother with either set up. Also to protect the electrical connections I have made a plastic cover out of a spray can plastic top with a hole drilled to allow the discharge pipe through. 

The positives are

easy access for maintenance

no smelly boot anymore

no diaphragm required 

hoses used are standard fuel hoses of the required diameter and I use jubilee clips - no leaks! 

negatives a little fiddley to fit.

not something you buy off the shelf.

cheers Andy

I don't want to hijack Ian's thread but can anyone tell me how I go about getting a Gates Barricade (or equivalent) high pressure hose made up for the standard Lucas set up. I know this has been covered before but I cannot find specifics on where to get the pipe, union types and sizes etc. If someone could tell me "this is who to go to and this is what to ask for" in true Noddy fashion I would appreciate it

I have just rebuilt the car with all new hoses and all kit re-conditioned by Neil F. It's only covered about 100 miles but I already have petrol smells in the boot which seem to be coming from the high pressure hose. All the smaller hose is barricade, bought from moss but the HP hose is Moss' standard 30R6 offering which not only smells but also whines like a coyote if routed across the wheel arch. Related to this, do I need to have clips on all the smaller hoses where they join to the copper or kunifer inlet and outlet branches?

Many thanks,

Sean

I had my P.I. kit restored by Neil and bought all new hoses from RevingtonTR, I bought their SS PRV - pump hose and I don’t have any fuel smell now.
