Rolling Roaded at last
Hi all.
FINALLY got around to having this done and it has made a massive difference.
Problem is i seem to be losing fuel pressure.
No leaks, tight bends, kinks, etc
Got the smallest facet pump fitted as near the tank as posssible.
I'm thinking of getting a larger pump and a regulator which should solve the problem and give me the extra bhp i'm losing.
Any other ideas before i go down this route?
Cheers
Rich
Time for a change!

Yep, use the R1 pump. That's what I used on Dan Mason's car and the RR results are very good.

I agree with Timc, a mate had the same problem on his blade engined indy, he dumped the facet and put a bike pump on and all is well again. He already
had the large facet pump with a filter king regulator.

Use the bike pump as stated already but with a carb engine don't you need the pump at the engine end not at the tank?

I think the tank end is best, I'm sure they are better at pushing than pulling

cheers folks
why use the R1 pump - wasnt it gravity fed from the tank on top?
I'd have thought a larger pump like bigger facet or red top type with regulator would do fine?
BHP was a misersble 105 but what a difference it has made to the car anyway
Time for a change!

Richard, you are still at least
20 bhp down on what it should be.
Something isn't right.

George, Its a fuel supply issue and not enough getting through as the revs pick up.
Pressure seems to be dropping off.
Bassett, it was done at BD engineering nr Sittingbourne
Time for a change!

Its not a great pic but if you look here:

You can just about make-out the fuel pump close to the forward lower wishbone bracket. It's mounted in a coil-pack bracket bought off ebay
(unless MNR have changed it.) I've heard of several people trying to use Facet pumps on BECs and having issues. All of these people have
solved them by going to the matched pump.

Use the standard R1 pump down under the tank on the bottom chassis rail. That way its gravity fed then pushes up to the motor.
Maybe the Facet cannot supply enough volume which drops the pressure.
Mate of mine had the same issue on a pinto with bike carbs, ditching the facet and using the OE pump has cured it.

does the standard pump use a positive and negative feed?
Time for a change!
