Sniper installed

[cj69RR]

Got some more time tis last week and got some good time in and installed the Holley sniper, with in tank pump. Didn’t wire it for timing control yet. But what a difference. Starting is awesome, so far it’s very good update. Didn’t get to drive it much because of the weather but performance is way better.

Wanted to do this for a while and got a good deal on this one. I’d recommend it to anyone who drives their car.

Update on the sniper, set the base timing on it with a good buddy and a good timing light. 15 at idle and 38 at 3k. put about 30 miles on it and no issues at all.

No return line with the Holley in tank pump sending unit. Not cheap but I think it's worth not using a return and I have two in use now. They have gone up in price https://www.holley.com/products/fue...uel_pumps/muscle_car_efi_modules/parts/12-314

Ok

Has anyone tried the surge tank style fuel delivery for EFI? From what I understand, it is a small unit located under hood that is fed by OE fuel pump, either electric or mechanical, and it raises the psi for the EFI.

it is called a sump pump . they have a few problems with heat and overflow. use an in tank pump with a return that is the best for life of pump / performance / quit ness

I know a guy with a Fitech with sump and it didn't work out well. He went to a pusher with return on his jeep.

Actually it is called a surge pump.

I would be curious as to the nature of the problems. Looking into efi for the ModTop. I thought it would be the easiest and completely reversible. Put the carb back on and reroute the fuel line from the original pump. Making it an easy bolt on conversion.

He had an early Fitech when they were having all kinds of problems, not sure what they are like now but he had ECU problems and loss of fuel pressure issues.

Yeah, zero interest in that. Wanting to use original air cleaner to maintain the factory look.
