Prevention is Better than Failure

[PeteGriff]

Hi guys - its been a while since I posted, thought it useful to show what I have been up to over winter months (Jan to March), before MOT time and back on road beginning of April. By the way, Griff sailed through MOT again, very pleased. Have also been busy with Griff Dashboards!

Firstly, I treated myself to a car lift (Strongman Tools Clifton Lift) for the garage, must say it made all the work carried out, including an oil & filter change a doddle!

When I checked the car over last year I noticed the hose from the tank to pump was showing signs of cracking, also the pump looked very old and crusty, plus I had never changed the fuel filter. So the plan was when laid up over winter to change all hoses, pump, filter and electrical connectors. It had not caused any issues (yet), but these things have a habit of biting you when you least expect it!

So, I went for a nice Sytec Motorsport pump, lovely quality and sized in capacity for the requirements of the engine, Motorsport quality braided hoses (ethanol resistant) supplied by my local hose specialist, Sytec fuel filter, crimped connections where possible and quality stainless clips. I used heat shrink sleeving over the braided hose cut ends, this gave a nice neat finish when shrunk down, the banjo connection to the outlet meant a better route for the hose to filter, finally the removal and replacement of the crusty old spade connector for nice crimped and soldered ring terminals and rubber boots. I also used a large rubber grommet to seal the hose where the hose came out from the tank through the bodywork. I drilled a 13mm hole underneath (shown in pictures) which enabled me to undo the clip on the tank union and tighten the new clip, this I finished off with a nice tight fitting grommet, the use of grommets gave a better job that loads of black mastic!

Note also that I made an aluminium clamp for the new pump, this clamps against the chassis rail and allows movement of the pump.

The Griff fired up first time once primed and having done about 30 miles now all seems good. Will be having a nice run to Burghley on Sunday, so a few more mile to test it out!

That looks great Pete! What made you decide on the Sytec pump over the standard Bosch unit?

Hi Matt, chose the Sytec unit because A) had good reports and Carsy has been using one for some time, B) really nicely made with a metal front and outlet using a banjo type connection (Bosch units appear to have plastic fronts and outlets now, C) units are Motorsport spec. It is quieter running also. Time will tell, but so far I am very pleased. Regards, Pete

Just a follow up - nice run to and from Burghley BHP, new installation faultless, that's a 200 mile test, so its good!

Note: Should anyone consider this setup I would be willing to make up an aluminium clamp kit for them, just like the one i have on mine!

Regards, Pete

I think you should offer this as a drive in / drive out service Pete.

Mmmm - TVR Stuff Specialist Centre?

What psi and flow rate did you go for Pete?

Hi Matt, it is the OTP020 Sytec Motosort Pump with a normal running pressure of 5 bar and a maximum of 10 bar. As I said previously the hoses are specialist types (not standard braided) sourced from a company near me who actually crimped up the connections required, all suitable for the modern fuels with ethanol. Regards, Pete

Good to see you and catch up at Burghley. Your Griff was looking immaculate. Nearly as nice as mine..

Good to see you also Moycie. Thanks for the comments re my Griff, yours was the inspiration for my interior retrim! I took loads of photos at the last Growl! All the best, Pete
