How did the pump affect mileage?

I thought it helped it on wvo,because the lift pump which is run by the motor,didn't have to work hard.

Got my injectors done by greazzer and scooped up one of his OFVs. Just installed the OFV and it made a noticeable difference...Highly recommended for my (turbo) application. I'll get the injectors installed sometime soon but wanted to see how the OFV did for the butt dyno first.

Currently, down to 5 new OFVs for turbo applications. All NA's sold out. After that, I just have the springs ...

Sending you a PM

Responded to. Thanks.

The idle smoothed out quicker after the first start of the day. Mind you, it's 65 degrees here and I'm comparing it to the last 10 or so days when the temp was lower. It also seemed to idle a little better.

Since I never push hard on the accelerator it's a little difficult to say how much the acceleration has improved. It runs great and seems to have quite a bit more pickup with this new valve. I just can't quantify it with objectivity. Me likie!

I'm not planning a trip to the post office until later in the week so you probably won't get the old bolt assembly until mid next week. Don't worry about the refund just take it off the price of popping those injectors when I get the new nozzles.

Thanks for the follow-up !

I've been reading this thread with interest .

Where does anyone tap in to test the pressure ? .

The hose from this banjo bolt goes up to the filter head and attached via another banjo bolt , I was thinking of drilling and tapping a spare one for a pressure gauge to see what's what before I spring for this modification .

Comments please ? .

Pictures of the pressure gauge tapped in would be nice too .

TIA ,

I haven't seen how people do it on these cars, but on a CIS gas system you switch one of the banjo bolts for one of these:

M10 x 1 0 Stainless Steel 20mm Banjo Bolt with 1 8" NPT Brake Light Switch Port | eBay

If there's an M10 banjo, that would work (haven't checked yet). Then you simply screw a 1/8" NPT pressure gauge onto it, or you could use an electrical sending unit to go to a gauge in the cabin.

Thank you ~

That's what I plan to do with a spare original brass banjo bolt , my Son's a Rice Racer and loaned me his old tiny fuel pressure gauge to screw into the drilled & tapped banjo bolt .

I wanted to ask before I made yet another foolish mistake .

Ought to work fine. I'm assuming that the gage will be visible to the driver? The engine needs to be under load to get meaningful readings so you want to be able to see it while driving (unless you're running on a dyno so you can read it with the hood up). I've seen commercially-made banjo bolts with a tap in the end (seems like they were 1/8" NPT) for just this purpose.
